Examples

If we remember that the extension of a concept is something like the set of objects that fall under the concept, then we could replace Frege's talk of ˜extensions™ by talk of ˜sets™ and use the following ˜set notation™ to refer to the set of objects that when added to 4 yield 5 and the set of objects that when added to 22 yield 5, respectively:

In some parts of Bavaria such bushes are set up also at the houses of newly-married pairs, and the practice is only omitted if the wife is near her confinement; for in that case they say that the husband has set up a May-bush for himself.

"Set (the verb) no longer the longest entry in the OEDFor many years the verb to set has been cited as the longest entry in the OED. But a recheck shows that it has at last been toppled from this position. The longest entry in the revised matter is represented by the verb to make (published in June 2000). However, it is quite possible that set will regain its long-held position at the top of the league of long words when it comes itself to be revised.

In ranking order, the longest entries currently in the online Third Edition of the OED are: make (verb - revised), set (verb), run (verb), take (verb), go (verb), pre- (revised), non- (revised), over- (revised), stand (verb), red, and then point (the noun - revised)."

The word set has a multitude of definitions in the English language (464 separate definitions according to the Oxford English Dictionary, making it the word with the highest number of definitions; its full definition contains over 10,000 words making it the longest definition in the OED).
